[ Upstream commit fd15594ba7d559d9da741504c322b9f57c4981e5 ]
The SoundWire IRQ domain needs to be created before any slaves are added to the bus, such that the domain is always available when needed. Move the call to sdw_irq_create() before the calls to sdw_acpi_find_slaves() and sdw_of_find_slaves().
